Punk has the same condition Bret has, being adamant that he's a pro's pro when in fact he's wildly self absorbed and borderline delusional. We'll call it "Favre Syndrome"

The difference between Bret and Punk is that Bret actually had a hell of a run and helped keep the ship afloat for a while. That's not an attempt to justify his ego, but it does explain how a sociopath like Bret Hart could end up the way he is; Bret Hart WAS extremely important for a long time.

As much as I loved him, CM Punk wasn't as important as Bret. In reality, he had a hot two years, but that's still two years inside of Cena's 10+ year window. (Tangentially, I actually think Daniel Bryan stands to be more important than CM Punk ever was, though he's yet to deliver on that promise largely in part to limpdick booking.)

We all know that eventually the WWE will pull the hoe card on an egomaniac - Bret, Warrior, and even Hogan can all attest to that. Now Punk's just had his number called, let's see how litigious he wants to get when he's the one on the defensive.
